mrsmackpaul Posted July 2, 2017 Share Posted July 2, 2017 I wouldnt think so Tim The only way to get more power is more fuel no matter what anyone says if all is working ok changing intercoolers wont help unless you change the injector pump settings to add fuel Paul Quote Link to comment https://www.bigmacktrucks.com/topic/50309-new-engine-or-new-truck/page/2/#findComment-373946 Share on other sites More sharing options...
Timmyb Posted July 2, 2017 Share Posted July 2, 2017 Fuel is one thing, but cooler, denser air from a more efficient intercooler would also make more power?

mrsmackpaul Posted July 2, 2017 Share Posted July 2, 2017 I think you will find it wont unless it has more fuel to make a bigger bang As the air is cooled it gets denser yes, but it wont achieve any extra power unless that air can be put to work by burning more fuel We all reckon things go better at night as the air cools but I think it mainly has to do with breeze dropping so the wind resistance is a lot lower Anyway that's my understanding but I could and most likely do have this all ass about Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/50309-new-engine-or-new-truck/page/2/#findComment-373955 Share on other sites More sharing options...

TeamsterGrrrl Posted July 2, 2017 Share Posted July 2, 2017 Mack upped the Maxidyne ratings by 5% when the switched to the chassis mount air to air intercooler.

TeamsterGrrrl Posted July 2, 2017 Share Posted July 2, 2017 Engine swapping can be challenging, even within the same family... from the early 70s through the last Mack engine in 2006 Mack added and changed intercoolers, went to a 4 valve per cylinder head, increased displacement to 12 liters, added electronic controls, and then changed everything around again! That said, went to a TDI club Get ToGether yesterday and saw a TDI engine swapped into a Ford Ranger... Lotsa work, but gets 40 MPG on the highway! Not easy, but the guy that did the swap is a Cummins engineer.

Phase 1 Posted July 2, 2017 Share Posted July 2, 2017 Air is fuel too. Add more air (oxygen) and you get a bigger bang. With a gas motor, if you add more air, you have to add more fuel to keep the ratio correct. A diesel will happily take more of either.

I'm about to talk myself into a newer truck.

Underdog Posted July 15, 2017 Share Posted July 15, 2017 Man, oh man it's your call, but $100k for a 10 year old truck?!? I couldn't do it... I have less than $20k into my MH and it's out there making money.

TeamsterGrrrl Posted July 15, 2017 Share Posted July 15, 2017 Nice truck, but the price is way high. And a "pre-emissions" 2007 E7? I've been hearing that claim a lot lately, They actually switched over to the MP engines late in 2006 so I doubt many if any pre-2007 emissions E7s were built.

Underdog Posted July 15, 2017 Share Posted July 15, 2017 I have noticed that, too. The latest selling point is anything without a DEF tank is "pre-emissions".

Timmyb Posted July 15, 2017 Share Posted July 15, 2017 The ad says mp7 doesn't it? Wasn't there a year with no emissions on the mp7? Sorry man I'm not familiar with it all but it's a nice looking truck.

Deere Mack Posted July 15, 2017 Author Share Posted July 15, 2017 I thought someone mentioned in this conversation that there were some early 07 MP7 engines with no current emissions. I looked back and couldn't find it. I think underdog is right, its pre to the current emissions law (DEF). I know its stepping out and I'm not 100% on the idea. I was up for an engine swap cause I know my truck, but buying and older truck and fixing someone elses problems doesn't sound to fun again. It's hard to find a dump that hasn't been road hard and put up wet..lol Especially when mack is the only truck in your radar. I've got to much work lined up and really need something ready to roll.....

Do $2,000 worth of injector/manifold/exhaust upgrades. Have a good reliable truck with no EGR/SCR/DOC/DPF headaches. Stay in top of AMI scale or into AI400, AI427 and AI460.

tjc transport Posted July 15, 2017 Share Posted July 15, 2017 (edited) i can see that with a county truck, they get more idle time than work time. i would steer away from that truck, way too much idle time.

Timmyb Posted July 15, 2017 Share Posted July 15, 2017 Can you get the litres of fuel burnt outta the computer? That would clear things up a bit. If they wanna sell it make them jump through some hoops. Get a blow by test done too. And a dealer should have a healthy profit margin so I'd definitely be knocking some off the price.

TeamsterGrrrl Posted July 17, 2017 Share Posted July 17, 2017 That 2008 with an AI427 may have been for export. Or they could have legally used a left over E7 by balancing it's emissions with credits from cleaner engines. Using old engines for export to markets with weak emissions is common- Had an ex-International and current Cummins engineer help me install a new exhaust system on my old TDI a couple weeks back, they both had stories of new old stock engines that didn't meet current emissions requirements here being put in trucks exported to countries with weak standards or installed in military trucks which are exempt.

Stands to reason. We have a complete (OEM) emission cancellation retrofit kit, hardware & software, that can be purchased and installed in our Volvo L180H to convert our 13 Liter for sale over seas. Our company has to show destination of foreign purchase, ship information, misc proofs, etc before it can be purchased.
